Here are today’s CHM 111 notes.  These notes include a few more examples of pH calculations with strong acids and bases.  I’ve also included the notes from our Q&A session for this Thursday’s test.

I’ve put the CHM 111 Test 2 grades into D2L.  Sorry for the delay!

Attention CHM 100 and CHM 111 students!

My daughter is sick, and I’ll need to stay home and take care of her on Monday, 3/8/2010.  Here is how this will impact your classes.

CHM 100: We will not meet for Monday morning’s class.  We will meet on Wednesday as scheduled.  Make sure you bring your quiz (that was originally due last Wednesday before the “winter weather” cancellation) to Wednesday’s c;lass.  Also, if you have not done so already, make sure that you have read all of Chapter 5 before coming to Wednesday’s class.

CHM 111:  Time to update your lab schedule again!  MONDAY LAB STUDENTS: The Monday lab section will not meet on 3/8/2010, and you will perform Experiment 12 after Spring Break.  TUESDAY LAB STUDENTS: The Tuesday lab section will meet as scheduled on 3/9/2010 – but we will not perform Experiment 12.  Instead, we will work on finishing the chloride lab we started last week.  We will perform Experiment 12 after the break.  ALL CHM 111 STUDENTS:  Click the link to get the updated lab schedule: [CHM 111 Lab schedule].  Everyone should check the updated lab schedule, since the date for the lab exam has changed.

We didn’t end up getting much winter weather, but …

FDTC will open at 10:30 AM. Since CHM 100 meets from 9:30 AM until 10:45 AM, this means that we will not meet for CHM 100 on Wednesday morning.

CHM 110 lab will meet at 2:00 PM as scheduled to perform experiment 4C.

This post will be updated as more information comes in.

Any questions?  Leave a comment here.

In CHM 100, we’ve recently been discussing the periodic table and the elements.  Just recently, a new element got its official name:  Element 112 is no longer Ununbium (Uub).  Now, it’s called Copernicium (Cn):

The suggested name “Copernicium” in honor of Nicolaus Copernicus (1473-1543) follows the tradition of naming chemical elements after merited scientists. IUPAC officially announced the endorsement of the new element’s name on Feb. 19, Nicolaus Copernicus’ birthday. Copernicus’ work in the field of astronomy is the basis for our modern, heliocentric world view, which states that the Sun is the center of our solar system with the Earth and all the other planets (in our solar system) circling around it.

As with most of the other extremely heavy elements, Copernicium’s nucleus almost immediately decays into other elements.  So don’t go looking for any copernicium down at Black Market Minerals!

My daughter’s not feeling well, so I will be staying home with her on 2/23/2010 (Tuesday).  Here’s how that will impact your classes.

CHM 100:  My absence shouldn’t have any effect on your class; I anticipate being back on campus tomorrow morning for class.  Quiz #4 is due tomorrow (2/24/2010).

CHM 110:  We’ll miss class today.  I had intended to cover molarity and the information you’d need to know to finish experiment 4C today in class, but we won’t have the opportunity.  So, we will slide the lab schedule back a bit to give us an opportunity to catch up.  We won’t meet CHM 110 lab this week, and will perform experiment 4C next week (3/3 and 3/4).  I will update the lab schedule to reflect this change.  The write-up for experiment 3B will be due when you come to lab to perform experiment 4C.

CHM 111:  We’ll miss class and today’s lab.  The Monday lab section will continue on their schedule like normal.  The Tuesday lab section will perform part 1 of the gravimetric chloride lab next week, and will finish part 2 of the lab on 3/9 along with the freezing point lab (there should be enough time to do part 2  at the beginning of the freezing point lab.)

Here’s the shared data from CHM 110 Experiment 3B. These are the ratios of mass product / mass barium chloride dihydrate that you need to complete the table on page 74 and answer the questions on pages 75 and 76.  This is data for the Wednesday lab section (section 2)!

Ratio of (mass product / mass BaCl₂.2H₂O):

• 0.89152
• 0.84770
• 0.84425
• 0.84847

The write-up for Experiment 3B is due at our next lab meeting. If you have any questions about either the calculations or the rest of the write-up, either come by my office or ask here in comments.

Here’s a handout that describes the calculation procedure for this experiment:

[CHM 110 Experiment 3B calculation notes]

I recommend that you use your TI-83 calculator or a spreadsheet to find the standard deviation the lab manual asks you to calculate.
